DVAS Instruction Manual Before You Begin EN 19

Stages of Array Mapping:

•Array Construct: Writes the RAID stripes to disk.

•Array Verify: Verifies that data can be read from each block of the array.

Dependant on disk capacity, it can take up to six hours to create a RAID Set.

6.7Adding and Mapping a Volume

NOTE: It is recommended to use the Quick Configuration page for adding and mapping volumes. This section may be used for future DVRs requiring more sophisticated volume mapping.

New arrays must be partitioned, via ADD VOLUME. A maximum of 16 volumes can be created (with a maximum of eight volumes per channel). Once a volume has been created, it must be mapped to a LUN or LUNs, and Host Channel or Channels.

To create a volume, click RAID, at the left-hand side of the main page, then select the Add Volume tab.

Figure 15 Creating Volume

Enter the name for the new volume to define the friendly name of the volume, for use in the GUI.

Enter the size of the new volume in

Megabytes (MB). You may create one volume that is the maximum size of the array, or a number of volumes. The remaining free space on the array is shown at the bottom of the screen.

Reserve an optional free space area at the beginning of the new volume for future expansion of a previous volume. A volume can only be expanded in this way. Data on a volume must be sequential; it is not possible to add data on an array unless it directly follows the volume.

Select logical unit number (LUN) for new volume on host 0/1. Use the drop down menu to define the LUN for each volume, on one or both Host Channels.

A LUN can only be accessed by one DVR.

To confirm your choices, select the Add Volume tab. To create more than one array, enter this page again using the left-hand menu.

Once the volumes have been created and mapped, restart the computer to access the DVAS Series disk array.
